IdentificationToothpick-plant typically grows 2-3 feet tall, with 2-compound (or more) divided leaves, the segments linear to narrowly lanceolate to filiform. The umbels are axillary and terminal, compound, the involucral bracts leafy. The flowers are tiny and white. According to RAB (1968), genus Ammi can be told from all of our other skinny segment genera by the umbel rays arising from a disk (vs. no disk). It is not keyed in Weakley (2018).
